Thanks for this parallel puzzle set--looks tough!

Questions regarding the IB:

2) For Araf Araf, do paired regions need to be adjacent?
10) For clarification on Double Double Back--grey lines between regions, if crossed, will count as an entry/exit, correct?

I feel clear on everything else. Looks like fun!

2) Yes. You're the second person to ask, so I'll add the clarification in the version with the points.
10) Yes. That's what the last line of the rules implies.

another question regarding the IB.
I find multiple solutions on both stostone and his bigger brother
for example in the second puzzle i can swap the shaded cells in (r2c1 and r3c2) moving them to (r2c2 and r3c1)
Is there anything I miss on the rules?

That would be invalid because of the "No two stones share a side" rule, and because the 4 clue would no longer be satisfied.

For puzzle 8, that would be invalid because when horizontal gravity is applied, the top two rows do not neatly form a 2x3 block.

Thanks to all 142 participants!

Congratulations to Endo Ken, Freddie Hand, Walker Anderson, Hideaki Jo, Kota Morinishi and Jeffrey Bardon for completing the set within the time. The top three remain the same from Parallel Universe III.

Among participants from India, Congratulations to Ashish Kumar, Swaroop Guggilam, Rajesh Kumar and Harmeet Singh for top four positions.

Among puzzles, not surprisingly, Stostone proved to be the toughest. Among squared Puzzles, surprisingly, Double double back proved to be the toughest.

Ovotovatatavotovo (like its spelling) was the most error-prone puzzle.

Thanks Prasanna Seshadri for the variety of puzzles in this test.

Thank you to everyone who participated in this as well as Parallel Universe 3. The last 2 installments were a challenge from the perspective of coming up with ideas that work interestingly within the respective themes and I'm generally happy with how things turned out and I am glad that people seem to have enjoyed the contests in general.

Congratulations to the winners. The top 3 have been the same across both contests, with just a swap between 2nd and 3rd places, which shows that these solvers are skilled at sprint solving as well as solving tougher puzzles. Really impressive performances.

Thank you to Rakesh, Murat, Philipp for their help with putting this together, and of course to Swaroop for his continued work on improving penpa-edit.

Feel free to ask doubts about the puzzles here :)

You can also see two videos covering puzzles on the contest so far.
Simon Anthony's runthrough of the Kakuro and the Kakuro Kakuro - https://www.youtube.com/watch?v=QBihIeXcL6I&t=1909s
Ashish Kumar's solve explaining the difficult logic on the Stostone puzzle - https://www.youtube.com/watch?v=_ghwaabIDk0
I recommend viewing both videos. They were both informative about the puzzles covered.
